Diaskintest for a runny nose: can it be done or not?

Side effects of Diaskitest and what to do if they appear?

Diaskintest is a modern drug that causes a minimum of negative manifestations, so phthisiatricians actively use it to clarify the diagnosis and identify mycobacteria. But still, sometimes some side effects may occur after diaskitest.

Possible side effects

Diaskintest should be carried out only by a competent nurse; this is the only way to reduce negative consequences. The drug is administered intradermally to reduce the penetration of the drug into the bloodstream. Despite the fact that adverse reactions are observed relatively rarely, you should not forget about them. They can be divided into two categories:

Manifestations are provoked by a specific response of the body to the administered substance.
Complications after diaskintest as a result of improper administration of the drug.

The body may react to the test:

Increased body temperature.
General malaise.
Allergic reaction.

Allergic rashes

With a strong immune system response, you can expect:

The hand turns red not only at the injection site, but throughout the entire forearm.
The appearance of a vesicle with purulent contents. Festering
A thick, red rash appears over the entire arm or body.
The injection site hurts.
Difficulty breathing.

Side effects are also possible if the injection technique is not followed. In this case, the following are observed:

Hematoma formation. A bruise appears if the test was made with a damaged syringe or the drug was administered too roughly. Hematoma
The appearance of a lump at the injection site. This happens if air gets in with the medicine.

As a rule, for children and adults, such consequences of the test are not dangerous to health and go away on their own within a few days.

The drug may also have side effects, including the following:

The digestive system after administration of the drug often reacts with mild nausea and discomfort in the stomach. Rarely, pancreatitis may worsen, stool changes, and dryness appears in the oral cavity.
From the nervous system side, headaches, increased nervousness and irritability are most often diagnosed. In rare cases, aseptic meningitis develops, but the risk of developing this symptom is high in patients with autoimmune pathologies.
Patients with cardiac pathologies often experience increased blood pressure and heart rhythm disturbances.
The respiratory system is rare, but may respond with shortness of breath.
Dyspnea
If you have kidney pathology, there is a high risk of developing kidney failure.

Why is Diaskintest dangerous for patients with allergies? There is a high risk of developing a nonspecific response of the body to the components of the drug.

What to do if there are serious side effects?

If contraindications are not taken into account or the technique of administering the drug is violated, or the conditions for its storage are not met, then severe allergic reactions may occur. As a rule, the first symptoms can be observed already on the day of drug administration. You should consult a doctor urgently if:

The rash affects not only the area around the injection site, but also spreads to the entire arm or body. Extensive rash over the entire body
Severe itching appears.
Malaise and significant rise in body temperature.
Dizziness and nausea.
Sleep disturbance.
Headache.

If these symptoms appear, only a doctor can determine the cause and prescribe appropriate therapy.

How to avoid side effects?

To exclude undesirable manifestations, it is important to approach the diaskintest thoroughly and prepare in order to avoid or mitigate negative consequences. The following recommendations can be given to patients undergoing this procedure:

A couple of days before visiting the doctor, start taking antihistamines, for example, Zodak, Zyrtec.
Eliminate foods that can cause allergies from your diet.
Consult a dermatologist first, especially if there are skin pathologies.
If there are somatic pathologies, undergo therapy first.
Take laboratory tests that can reveal hidden diseases that can negatively affect the test result and cause side effects.

Any preventive measures should be taken only after consultation with a doctor and if there is a need for them.

You should not be afraid of Diaskintest; it allows you to identify pathology at the earliest stages of development and take the necessary measures. The test is most often well tolerated by the body; most complications and negative manifestations are caused by non-compliance with contraindications and the technique of administering the drug.

Who makes the decision to conduct the test?

The decision whether to perform a Diaskin test or not is made jointly by the doctor and the patient. When the test is given to a child, the pediatrician makes the decision about the need for vaccination, but the final word remains with the parents.

After performing Diaskintest, there is a possibility of side effects:

loss of appetite;
weakness;
slight headache.

In a normal situation, these symptoms disappear after two to three days, but if this does not happen, or the child’s condition worsens, you should immediately consult a doctor.

If you refuse Diaskintest due to temporary or absolute contraindications, you will have to be tested for tuberculosis in the form of fluorography or x-ray.

Diaskintest: side effects, consequences for children and adults

Diaskintest is the latest proven medicine aimed at the early diagnosis of tuberculosis. Many people think that it replaces the long-known Mantoux test, but this is not entirely true.

Today, Diaskintest is often an additional measure to more accurately confirm the diagnosis, although it can also be used as an independent method.

Features of use and contraindications

Diaskintest is a solution for intradermal administration only. Contains synthetic proteins similar to those of the main causative agent of tuberculosis - mycobacteria (MBT).

All foreign proteins introduced into the human body are regarded by the immune system as an allergen. This is what Diaskintest is designed for.

In this case, an allergic reaction is assessed, which is more pronounced in people with tuberculosis.

Diaskintest is a modern development, the use of which minimizes the risk of side effects and provides maximum assistance in diagnosis. Before prescribing it, the phthisiatrician must take into account the indications and contraindications for the administration of this drug.

Indications for Diaskintest injection are:

identification of tuberculosis with its activity level;
assessment of treatment dynamics in persons with a confirmed diagnosis;
differential diagnosis of tuberculosis;
false positive or positive Mantoux test.

Contraindications to the administration of Diaskintest can be absolute and relative. In the second case, the doctor evaluates the expected risks and benefits of the test. If you ignore any of them, a lot of adverse reactions may occur that can significantly worsen the patient’s health.

The following are considered absolute contraindications:

any acute infectious and inflammatory disease in the patient;
cold;
skin diseases, especially in the acute stage;
history of epileptic seizures;
active allergic reaction (rhinitis, conjunctivitis, skin itching of food or any other origin);
exacerbation of any chronic diseases of the lungs, stomach, intestines, kidneys;
preventive vaccinations (including repeated or primary administration of BCG) during the previous month;
for young children – a period of active tooth growth, especially accompanied by a temperature reaction;
quarantine period, especially in large gatherings of people (kindergartens, schools);
children's age up to 1 year.

Pregnancy and lactation are considered relative. The presence of such a large list of contraindications significantly limits the use of this drug for mass routine diagnosis of tuberculosis infection. It is often prescribed in conjunction with the Mantoux test.

If the doctor adequately assesses the situation in each specific case, taking into account the existing indications and contraindications, then the risk of developing adverse reactions is minimal.

Negative reactions of the body

This drug is administered by specially trained personnel. The area for injection, carried out with a small syringe (insulin), is the inner surface of the middle third of the forearm.

As already mentioned, the drug is administered only intradermally. With this injection route, the development of adverse reactions is minimal, which is associated with a small intake of the drug into the bloodstream.

However, no one is immune from unwanted consequences.

Types of Side Effects

When Diaskintest is administered, side effects do not occur often.

They can be divided into two groups:

Associated with the body's response to the administered drug.
Occurring due to incorrect testing technique on the part of medical personnel.

The first group includes:

slight increase in temperature;
development of malaise;
allergic reactions.

If an allergy develops, the following may occur:

severe redness of the injection site, spreading to the entire forearm;
the formation of an abscess where the injection was made;
skin rash all over the body, thicker where the drug was injected;
runny nose, sneezing;
irritation, the injection site may itch;
labored breathing.

All this can occur due to individual intolerance and allergy to one of the components of the drug. The skin rash is itchy and itchy, which causes a lot of inconvenience to a person. Hyperemia can spread to the entire arm, accompanied by the formation of blisters with clear liquid.

If one of the above symptoms occurs, you should seek medical help as soon as possible. The doctor will prescribe the necessary treatment, which must include antiallergic medications. The test results are not evaluated.

Due to a violation of the Diaskintest injection technique, the development of side effects comes down to:

hematoma at the injection site;
"bump" on the skin after the injection.

The “lump” is a bulge where the drug was injected. It can occur due to the introduction of air along with the medicine and is called subcutaneous emphysema. She may not itch. Does no harm. Dissolves quickly within 1-2 days.

A bruise at the injection site can occur as a result of damage to a blood vessel with a needle or rough administration of the drug using a low-quality syringe. This condition does not affect the assessment of the result and does not require medical intervention. Goes away on its own within a few days.

How to prevent the development of adverse reactions

If a patient is scheduled for such a procedure, the doctor can give certain recommendations to better prepare for it. This is especially important for people prone to allergic reactions and having concomitant pathologies of internal organs.

Before performing the test, doctors may prescribe:

antihistamines (Zodac, Zyrtec, Claritin) in standard doses 2-3 days before drug administration;
hypoallergenic diet;
if necessary, consult a dermatologist;
laboratory research.

A general blood and urine test is also advisable before the injection. In this case, some hidden forms of diseases may be detected, which may be aggravated by the administration of Diaskintest.

It should be noted that the listed measures help not only prevent the development of adverse reactions, but also reduce the possibility of a questionable result when assessing a sample associated with the individual characteristics of the body. Only a doctor can prescribe these measures, taking into account their actual need.

It is important to know: slight hyperemia and compaction at the site of Diaskintest injection are not side effects of the test! These are the main indicators for assessing the result on the 3rd day after the injection.

Diaskintest is a fairly safe method that helps improve the mass diagnosis of tuberculosis. All of these side effects are extremely rare and, as a rule, develop as a result of ignoring contraindications. Therefore, the doctor must first comprehensively assess the patient’s condition before prescribing the drug.

Is it possible to do Diaskintest for colds and runny nose, will it do any harm?

People who decide to choose an alternative way to test for tuberculosis are usually faced with the question of whether Diaskintest can be done for colds, coughs, allergies and other common diseases, the aggravation of which often occurs during the vaccination period.

When is it worth taking a test for tuberculosis, and when should you refuse it? You can do Diaskintest for colds in children and what side effects exist.

Is it possible to do Diaskintest with a runny nose?

A runny nose is a common disease that most often plagues people in the autumn-spring period, and some “lucky” people suffer from inflammation of the nasal mucosa in the warm season.

The main causes of a runny nose:

Acute respiratory viral diseases. Inflammation begins due to the activity of viruses and bacteria. It is often accompanied by other unpleasant symptoms: cough, fever, headache, weakness.
Allergy.
Sometimes allergic rhinitis does not cause serious inconvenience, but more often it is severe, accompanied by coughing and swelling. It depends on the strength of the body's reaction.
Increased sensitivity of the mucous membrane.
In this case, a short runny nose occurs, caused by external irritants: strong, unpleasant odors, temperature fluctuations, dust, dry air.
Chronic rhinitis caused by congenital or acquired diseases.

Not all of these reasons become a contraindication to diaskintest.

In case of a cold caused by an infection, it is recommended to postpone this test, but increased sensitivity is not a limitation for it. A runny nose sometimes becomes a side effect of the test itself: this is how the body reacts to the drug injected into the blood.

Parents often ask whether Diaskintest can be done for a runny nose, especially for a child. However, tuberculosis not diagnosed in time will cause much more harm to health, so it is worth getting tested even with a mild form of rhinitis, unless a doctor prohibits it.

Is it possible to do Diaskintest for a sick child?

Before the test, both adults and children undergo a medical examination. A health check is necessary, since it is impossible to do a diaskintest if you are ill, especially with damage to the respiratory tract.

Restrictions are necessary due to the nature of the test. During the procedure, instead of a pathogen, genetically modified proteins are introduced into the blood, causing a reaction only if the tuberculosis bacillus is present in it. In an organism affected by pathogens, the immune system is activated to fight pathogens, which distorts the test results.

Vaccination against the background of the disease causes the following side effects:

allergy;
increased symptoms of the disease;
decreased immunity;
heat;
compaction at the injection site.

There is no point in doing a test during illness, but the doctor may suggest performing the procedure if there is a slight runny nose unaccompanied by other symptoms. In this case, the choice of whether to give the baby a test or to postpone the procedure remains with the parents.

However, no specialist will insist on conducting a test in the midst of an epidemic.

Is it possible to do Diaskintest if you have a cold?

Testing for tuberculosis when you have a cold is not recommended. The presence of infection in the body is likely to distort its effect. Colds often cause a false-positive result, and further tests do not detect tuberculosis.

A cold can easily develop into or be the first symptom of any serious respiratory disease. Complications that can harm all body functions are also possible.

The following side effects occur as a consequence of getting vaccinated during a cold:

Increased symptoms.
Headache.
Nausea.
Dizziness.

A cold, no matter how mild it may seem, is an absolute contraindication for Diaskintest. Vaccination should be postponed until complete recovery.

Is it possible to do Diaskintest for coughing?

The cough itself is only a symptom. It occurs for various reasons, which include:

cold;
acute respiratory diseases;
stress;
osteochondrosis;
cardiovascular diseases;
increased stomach acidity;
smoking.

All this is related to health problems, but only in case of cough caused by a cold or infectious diseases, the discintest is contraindicated.

In some cases, "smoker's cough" may be a sign of chronic bronchitis. An examination is necessary to find out for sure.

Before getting vaccinated, you need to determine the cause of your cough, then the doctor will be able to tell you for sure whether you can undergo the test. The cough that appears after Diaskintest is most likely an allergic reaction.

Is it possible to do the Diaskin test at a temperature

If elevated temperature is a symptom of an infectious disease, diaskintest cannot be performed.

In the case when the temperature is not accompanied by other signs of a cold, the reasons are as follows:

stress;
increase in external temperature;
physical activity;
any injury (cut, foreign body, frostbite, burn);
spoiled food;
allergy;
drinking alcohol or hot drinks.

There are no visible contraindications for vaccination. However, it is advisable to postpone the test at a temperature, since it itself sometimes provokes an increase in temperature against the background of an allergic reaction.

In women, fever sometimes occurs during menstruation. In this case, it is recommended to postpone the Diaskintest until completion in order to avoid a false positive reaction.

Is it possible to do Diaskintest for allergy sufferers?

Diaskintest is carried out for chronic allergies. Bronchial asthma, dermatitis, allergic rhinitis and food intolerance are not an absolute contraindication.

However, the test can cause an allergic reaction, like any medication:

Redness at the injection site, spreading redness to the entire forearm.
Purulent formations.
Skin rash, itching.
Labored breathing.
Runny nose, cough.

If a severe allergic reaction occurs, you should immediately consult a doctor. The sample results will not be evaluated.

If you know you have an allergy, tell us before the test, even if the allergy test is negative.

To avoid side effects, allergy sufferers should prepare in advance for vaccination: a week before the test and for several days after it, have as little contact with pathogens as possible, and take antihistamines.

Is it possible to do Diaskintest immediately after an illness?

A decrease in symptoms and an improvement in well-being does not indicate a final victory over the disease. The infection, although suppressed, may still be present in the body. Most often this concerns colds: the medications taken for them are mostly intended only for a general improvement in well-being.

For those wishing to carry out a diaskintest after an acute respiratory viral infection or other illness, the time when it can be done without fear of getting a false result cannot be specified precisely.

First you will have to undergo a medical examination and pass the following tests:

blood;
feces;
urine;
mucus from the nose.

If the test does not reveal the presence of infection, a test for tuberculosis can be done a month after recovery to allow the body to fully recover.

Additional tests are also necessary to detect hidden infection or microbial carriage. In both cases, the pathogen is present in the body, or causes an asymptomatic course of the disease, or is in a state of equilibrium with the host without stimulating its immune system.

When can you do Diaskintest?

Due to the small number of side effects and the low probability of their occurrence, Diaskintest is almost safe for health. It is recommended for elderly people, pregnant and lactating women. Even a one-year-old child can be tested for tuberculosis safely using this method. The sample does not contain the causative agent of the disease, but antigens present in strains of the tuberculosis bacillus.

Diaskintest checks the body for the presence of tuberculosis bacteria, which can cause this disease in the future. This differs from the Mantoux test, which can also react to traces of Koch’s bacillus in the blood, even if there are no microorganisms themselves in it.

The test is allowed if the patient does not have infectious diseases or other serious pathologies.

He is appointed:

People at risk. It is determined by environmental, social, medical and epidemiological factors.
People living in places where tuberculosis is widely detected.
For children under 17 years of age, as an annual scheduled check.

Diaskintest is allowed to be carried out a month after another vaccination.

In case of a negative result, a repeat test is prescribed no earlier than two months after the first test.

Many people wonder whether it is necessary to follow a certain diet after vaccination, giving up sweet, fatty foods, and alcohol. Doctors recommend that people with allergies avoid eating foods that cause an allergic reaction.

However, there are no restrictions for healthy people. Drinking alcohol also does not affect the results of the Diaskintest, but increases the risk of side effects such as pressure surges, headaches, hardening at the injection site, or even fever.

In what cases is it better to postpone Diaskintest?

Diaskintest is more sensitive than the Mantoux test, but it is seriously influenced by the individual characteristics of the patient’s body, his state of health and external factors.

In what cases is it better to refrain from vaccination:

For infectious diseases, colds, rhinitis. The presence of pathogenic organisms in the blood provokes a false-positive or false-negative result, so doctors recommend postponing the diaskin test until complete recovery and require additional tests.
During pregnancy.
Cases of individual intolerance to the components of the drug are rare, but possible, so it is better not to do the test while you are expecting a child if you are not at risk.
Allergy.
Diaskintest is not contraindicated for allergy sufferers, however, without prior preparation, its completion will cause complications: a severe allergic reaction, acute bronchitis, tracheitis. It is advisable to refrain from vaccination during the period of active pathogens.
Quarantine period. If there is a high probability of contracting an infectious disease, doctors themselves recommend postponing the procedure, as it will most likely give a false result.

If the doctor insists on taking the test, despite contraindications, make sure that information about the current state of health is fully included in the medical record.

Who makes the decision to conduct the test?

After performing Diaskintest, there is a possibility of side effects:

loss of appetite;
weakness;
slight headache.

In a normal situation, these symptoms disappear after two to three days, but if this does not happen, or the child’s condition worsens, you should immediately consult a doctor.

If you refuse Diaskintest due to temporary or absolute contraindications, you will have to be tested for tuberculosis in the form of fluorography or x-ray.

Is it possible to do Diaskintest immediately after an illness?

First you will have to undergo a medical examination and pass the following tests:

What is Diaskintest and contraindications for children?

Diaskintest is a modified version of the Mantoux test, which allows you to diagnose tuberculosis with greater accuracy than the classic tuberculin test. This study is recommended mainly for children, so many parents are interested in advance about what it is, what is dangerous about administering the drug, and what contraindications exist.

Contraindications to the administration of the drug Diaskintest can be absolute and relative: the former are caused mainly by allergies or chronic pathologies, and the latter by acute infections or immunization.

At what age can you do it?

Diaskintest can be done from the age of 1 year, but it begins to be performed on a regular basis no earlier than 8 years. For infants, the test can be not only useless, but also dangerous: the child’s immune system is not mature enough, so it is not easy to predict the reaction to the administration of modified tuberculin.

In preschool institutions and primary schools (up to 7 years old), this test is replaced by the traditional Mantoux test.

This study is less accurate, but allows for the diagnosis of immunity for revaccination at 7 years.

By this time, in many children, the Mantoux test becomes questionable or positive, so after the 8th birthday, doctors recommend Diaskintest as a more accurate test for tuberculosis.

When a positive Mantoux result is obtained in children under 7 years of age, it is done as a differential diagnostic method.

This is due to the fact that with Mantoux the number of false positive reactions is 20-30%, with Diaskintest - less than 2%.

Diaskintest is not carried out for preventive purposes for people over 18 years of age. Even in the absence of contraindications in adult patients, it is being replaced by a more effective and inexpensive method - fluorography.

The radiation dose during the annual procedure is not harmful to an adult body. In this case, positive results of Diaskintest in all cases require additional radiographic examination.

When you can and cannot do it

Indications for Diaskintest are the following cases:

annual preventive examination of children from 8 years of age;
detection of latent tuberculosis infection (determining the risk of developing an active form when infected with mycobacteria);
differential diagnosis of tuberculosis with a positive or questionable Mantoux test and a tendency to allergic reactions;
monitoring the effectiveness of anti-tuberculosis treatment.

Children with immunodeficiency and metabolic disorders (for example, diabetes mellitus and gastrointestinal ulcers) are at risk of developing tuberculosis, so for them the recommended frequency of testing may be 2-3 times a year.

When using Diaskintest for monitoring purposes, there are no restrictions on the frequency of the study. To obtain a reliable result after suffering from tuberculosis and a positive reaction to the test, you need to repeat the test at least 2 months later.

Diaskintest cannot be done for the following indications:

hypersensitivity to the components of the drug, a history of pathological reactions to the test;
epilepsy;
exacerbation of chronic diseases of the body, incl. pancreatitis, cardiovascular pathologies, bronchial asthma, etc.;
acute viral, bacterial and other infections (pyelonephritis, hepatitis, bronchitis, pharyngitis, scarlet fever, chickenpox, tonsillitis, giardiasis, etc.);
exacerbation of skin diseases of an allergic nature (neurodermatitis, psoriasis, dermatitis), rashes of any etiology (pustules, urticaria, etc.);
hyperthermia;
quarantine at school or at home;
immunization with any vaccine (at least 1 month must pass from the moment of vaccination to Diaskintest).

If the patient has relative contraindications to Diaskintest (infections, exacerbation of skin diseases, seasonal allergies, vaccination, etc.), the examination should be postponed for 1-2 months. The timing of the test is determined by the pediatrician or therapist.

In case of absolute contraindications (epilepsy, pathological reaction to the drug), Diaskintest is prohibited on an ongoing basis. In doubtful cases, for example, in case of any chronic pathologies of the central nervous system, it is necessary to consult with your doctor before administering the sample.

Is it possible if you have a cold?

Diaskintest is not recommended for colds. To get a reliable result and avoid excessive sensitization, you should completely cure the disease and take a short break before performing the test.

The reason for temporarily refusing the test can be not only fever, severe sore throat and other obvious symptoms of a cold, but also the first signs of the disease - malaise, weakness, chills, headache.

Important information: What is the Mantoux norm for children aged 2 years?

At a temperature

Hyperthermia, or increased temperature, is a strict contraindication to Diaskintest.

Before administration of the drug, the temperature of all patients is measured.

If the study is carried out for preventive purposes, even at low-grade body temperature (+37.1°C...+38°C), it is recommended to refuse it.

Is it possible for a cough?

The most common causes of cough in both children and adults are ARVI, colds, bronchitis and laryngotracheitis. These diseases of the respiratory system are relative contraindications to the test.

However, for persistent, frequent and hacking cough, this study may even be recommended. This phenomenon is called staccato cough and is one of the early signs of tuberculosis.

An additional reason to prescribe the Diaskintest test for cough is the presence of other symptoms of a dangerous disease - malaise, severe night sweats, weight loss, loss of appetite, pallor, etc.

Is it possible to do this if you have a runny nose?

Like a cough, a runny nose often accompanies infectious inflammation of the upper respiratory tract. Nasal congestion and active secretion of mucus are caused by an immune reaction to the penetration of pathogens into the mucous membranes.

The second common cause of a runny nose is the manifestation of an allergic reaction (drug, dust, epidermal or seasonal).

Reactions to allergen and infection belong to immune mechanisms, therefore Diaskintest for a runny nose is not recommended, regardless of the reasons for its occurrence. In case of chronic rhinitis, an invasive test can be replaced by a hardware examination (fluorography).

After illness

After an illness caused by an infectious factor, pediatricians recommend taking a break of 1 month. Diaskintest after ARVI can give a false positive result, which will entail additional examinations that are harmful to the child’s body.

During pregnancy

The effect of tuberculin tests on the fetus has not been sufficiently studied, therefore Diaskintest is rarely prescribed during pregnancy.

In immunocompromised conditions and the presence of other risk factors, administration of the drug during pregnancy is permitted as a safer alternative to radiation. In this case, the expected benefit for the mother must exceed the possible negative impact on the development of the fetus.

What not to do after Diaskintest

Diaskintest results are assessed 3 days after the injection. To exclude a false positive test result, you must follow the following rules:

do not rub the skin in the injection area after washing;
do not apply cosmetics (soap, shower gel, body lotion, cream, perfume, etc.) to the injection area;
do not cover the injection area with a compress, bandage or adhesive plaster;
when regularly applying medications to the injection area, temporarily abandon this measure or warn the doctor;
exclude possible allergens from the diet (especially for children) - citrus fruits, seafood, eggs, strawberries, etc.;
do not wear constrictive, itchy woolen or allergenic synthetic clothing;
avoid hypothermia, overheating and visiting crowded places;
do not rub or scratch the injection site; if itching, use antihistamines (Loratadine, Suprastin, etc.);
temporarily give up active sports;
exclude visiting the pool, bathhouse, sauna, solarium and beach;
do not drink alcohol.

Contact with water and touching the skin at the injection site does not affect the result of the study.

Why is it dangerous?

The test preparation contains a modified tuberculosis antigen and preservatives that preserve its activity (phenol, polysorbate, potassium phosphate). In rare cases, these components can cause side effects - headache, slight fever, weakness, tearfulness, etc.

According to reviews from pediatricians, allergists and TB specialists, in the absence of contraindications, Diaskintest is not harmful to health. Side effects of the drug can be controlled with antihistamines.

The use of Diaskintest after insufficient examination of the child or in the presence of contraindications can cause more dangerous consequences:

worsening skin pathologies (itching, crusting, urticaria, peeling, etc.);
neurological complications;
increased risk of viral infections and exacerbation of somatic diseases;
anaphylactic shock.

If any complications occur, you should contact your pediatrician. If a child has a temperature of +39°C or higher, convulsions or other emergency conditions, you should immediately call an ambulance.

How can you refuse the study?

Adult patients and guardians of minors are allowed to refuse prophylactic Diaskintest. Refusal to conduct a test must be made in writing.

In this case, the patient is sent for a consultation with a phthisiatrician and alternative diagnostics (lung x-ray), based on the results of which a certificate of health is issued.

It is not recommended to refuse the test without contraindications and complications in family and individual history, because Diaskintest is one of the most accurate methods for detecting latent tuberculosis.
